Abstract
A systematic study of TSEE curves obtained after UV or X irradiations at 77 K from alumina samples of various origin is reported. These curv es are systematically compared with TL glow curves recorded in similar conditions. Nine positions for thermostimulated peaks are detected in the 77 to 600 K range. These peaks appear with various occurrence fre quencies. Except for the first peak (100 K, peak A) which does not exi st in the majority of the TSEE curves recorded, the main TSEE peaks co incide fairly well with the correspondent TL peaks. A mechanism is pro posed to interpret the behaviour of peak A.
